As Dave noted, it's a non-recursive grant. It isn't changing the
permissions for C:\ and everything under it. It's only changing the
permissions for C:\ its self. It's then stepping down the path of
parents down to the datadir and doing the same thing to make sure you
have the required rights on every folder all the way down.
See: http://technet.microsoft.com/en-us/library/cc753525(WS.10).aspx
and note the lack of the /t flag when icacls is called.
I ran another install and monitored what the process was doing and it *is*
recursively touching all files on my harddisk when
icacls C:\ /grant "tkellerer":RX
is called. Even without the /t switch.
I verified this using ProcessExplorer displaying the open file handles for the
running icacls.exe
So there is either some (hidden?) system setting that makes icacls to recurse
by default or something has changed in Windows7.
I can see the exact same behaviour (touching all files recursively) when I run
the above command manually from a command prompt

Thomas
